Do all managed switches come from the factory with all of their configuration settings disabled?

The statement that all managed switches come from the factory with all of their configuration settings disabled is not accurate. Different manufacturers have varying practices regarding the default settings of their managed switches.

Many managed switches do come with certain default configurations that might include basic settings for VLANs, management IP addresses, or even access controls to facilitate initial setup and usage. This approach allows users to get started quickly or to adhere to standard networking practices. Therefore, the notion that all managed switches are completely unconfigured from the factory is misleading, as it largely depends on the manufacturer and the specific model of the switch.

In contrast, some managed switches may come with configurations minimized to prevent security risks, requiring users to make adjustments based on their needs. The variability underscores the importance of checking specific manufacturer documentation for details on factory default configurations.
